INSTALLATION
|
|
|
|
Place files SCSTTarget and SCSTLun into pacemaker ocf directory (usually
|
|
/usr/lib/ocf/resource.d or /usr/lib64/ocf/resource.d)
|
|
|
|
|
|
|
|
EXAMPLE OF USAGE
|
|
|
|
Assumptions:
|
|
- you are using DRBD as backing device (/dev/drbd1)
|
|
- your target iqn is iqn.2012-02.com.mysuperhasan:vdisk.lun
|
|
- your nic reserved for iscsi is eth2 and your iscsi subnet is 192.168.103.x
|
|
|
|
This is what your resource configuration in cib notation will look like:
|
|
|
|
primitive DRBD_VOLUME ocf:linbit:drbd \
|
|
params drbd_resource="DRBDRESOURCE" \
|
|
op monitor interval="29" role="Master" \
|
|
op monitor interval="31" role="Slave"
|
|
primitive ISCSI_IP ocf:heartbeat:IPaddr2 \
|
|
params ip="192.168.103.20" cidr_netmask="24" nic="eth2" \
|
|
op monitor interval="10s"
|
|
primitive ISCSI_LUN ocf:scst:SCSTLun \
|
|
params target_iqn="iqn.2012-02.com.mysuperhasan:vdisk.lun" lun="0" \
|
|
path="/dev/drbd1" handler="vdisk_fileio" device_name="VDISK-LUN10" \
|
|
additional_parameters="nv_cache=1" \
|
|
op monitor interval="10s" timeout="120s"
|
|
primitive ISCSI_TGT ocf:scst:SCSTTarget \
|
|
params iqn="iqn.2012-02.com.mysuperhasan:vdisk.lun" \
|
|
portals="192.168.103.20" \
|
|
op monitor interval="10s" timeout="120s"
|
|
group GR_ISCSI ISCSI_TGT ISCSI_LUN ISCSI_IP
|
|
ms MS_DRBD_VOLUME DRBD_VOLUME \
|
|
meta master-max="1" master-node-max="1" clone-max="2" \
|
|
clone-node-max="1" notify="true"
|
|
colocation CO_ISCSI_ON_DRBD_VOLUME inf: GR_ISCSI MS_DRBD_VOLUME:Master
|
|
order OR_DRBD_BEFORE_ISCSI inf: MS_DRBD_VOLUME:promote GR_ISCSI:start
|
|
|
|
|
|
|
|
CURRENT LIMITATIONS
|
|
|
|
Scripts are tested only with straight drbd or lvm over drbd as backing device,
|
|
using vdisk_fileio, with one lun per target.
|
|
|
|
CHAP authentication is configurable, but not yet tested. My current version of SCST
|
|
throws an error while adding chap parameters.
